This grant will be used to develop and evaluate a decision analysis based intervention to improve decision-making among veterans with newly diagnosed localized prostate cancer. While the ultimate goal of this study is to improve decision-making among these patients, factors influencing physician recommendations for treatment will be sought. The former will be achieved by evaluating the efficacy of providing physicians with information incorporating patient preference for alternative health states with probabilities of treatment outcomes. Factors influencing physician recommendations for treatment will be determined through qualitative interviews with physicians.
